To a]? whom it may concern:

Be it known that I, Janus A. Hrarucn, a citizen of the United States, and residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Gas Producers, of

This invention relates to apparatus for making producer gas, and one of the objects of the invention is to provide new and improved means whereby the mass within the producer will be thoroughly and continuously agitated, thereby insuring'a complete consumption of'the fuel, and a uniform flow or" gas.

Other objects will be in part obvious, and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts, which will be exemplified in the construction hereinafter described, and the scope of the application ofwhich will be indicated in the following claims.

In the accompanying drawings: Figure 1 is a view invertical section, showing a preferred embodiment of my invention; Fig. 2 is a view partly in plan andpartly in section of said embodiment; and Fig. 3 is a. view partly in elevation, and partly in section, showing a detail of construction,

Similar reference characters refer to similar parts throughout the several figures of the drawings.

Referring now to the drawings, the shell or casing of the producer is illustrated at 1 and is provided with an arched cover portion 2. Leading from the casing is a conduit 8, through which the producer gas is dis charged, the lower end of the casing being lower'at the bottom as at 4, to permit of the ashes being discharged in thedepression 5 formed beneath the same in the foundation of the producer. The ashes are removed from this receptacle through a passage way 6, extending about the lower end of the pro ducer. The receptacle 5 is,adapted to contain the water, which forms a seal for the lower end of the producer, thereby preventing a leakage of gas. Extending radially into the interior of the producer are'twyer boxes 7, in the present instance three of these boxes being provided, as shown in Fig. 2 of the drawings. Each of these twyer boxes is connected with a source of blast supply 8, and each box is provided with openings as at 10, through which the blast may pass into the interior of the producer. Mounted upon each twyer box, as by means of the journaled bearing 9, formed intogrally thereon, is a stirring device 11, each stirring device being provided with a pair of divergent legs 12 and 13, said legs being preferably set at a different angle from the vertical, as shown, (me being longer than the other; such construction insuring that these logs shall pass through a different portion of the mass during the operation of the producer. Each of these stirring devices is also provided with a pair of oppositel disposed legs it and 15, primarily intent ed to prevent the formation of clinkers above the twyer boxes. These legs also aid in the agitation of the mass, and also assist the discharge of the ashes through the aveend of the producer. Depending from the cover portion 2 of the producer, in the pres ent instance, are three stirring members 16, each. of which is provided at its upper end with a gear 17, which rests upon the cover portion, forming a support for the stirring member-I .These members 16 are likewise provided with divergent legs 18 and 20, set at different angle from the vertical, one being longer than the other as in the stirring members mounted on the twyer boxes. Stirring members 11 and 16 are. set in alternate relation, as shown in Fig. 2 of he drawings. The stirring members 11 mounted upon the twyer boxes? are each provided with a dependent hollow shaft 21, suitably journaled in the twyer boxes, the lower end of which is provided with a bevel gear wheel :22, the same meshing with a bevel gear wheel 23 carried upon a shaft 24. The opposite'end of shaft 24 is provided with beveigear 25, the same meshing with a suitably supported bevel 1831126 upon the shaft 27, the driving means of which will be hereinafter more particularly described. Each of shafts 24 which extend into the producer protected, as by means of tube 28, one end of which is closed andthe other open where it is joined with its twyer box- Apertures as at 30. are provided in the lower wall of this tube from which blast fiowing into this tube from the twyer box, may be discharged into the interior of the producer The stirring devices 16fwhich depen from the cover of the producer aretochl THE of the casin and t moopvc dri en j of 'hich m- 2?; the.

as'of gear wheel 31, each cal uponcnc of the. shafts hree' of these shafts provided, for driving each pair of upper or lower sirring devices. Gear Wheels 31 mesh with idleiwgesr wheels 32, suitably journcled won the cover ortion lies'e irll'ers mes with gear wheel 1 mounted noon the upper cud of the hollow shafts which carry stirring member 16. fine oi the shafts 27 is provided at its lower .end' with a bevel goo; 33,-whicn is driven as by means of a similar gear wheel 3i upon shaft 35, r'l'erivin its power from any suitable source. This s raft at its upper end is provided with bevel-gear wheel 3'6, nieshringwithbevel gear wheel 37 upon shaft 38,

which shaft is provided at its opposite and with a bevel gear 45, which meshes with a similar gear 41 provided upon the hollow shaft 42. This lgtt'cr shaft extends downward Lthrough the fuel hopper 43, and its lower and carries the'iuel distributing devices 44 adopted at the central l-which will not be Yartioularly described 25, t

Stirring members and associated parts are water cooled inihe following manner: 50 indicates eeveter scpuly pipe provided with the swivelcd joint 1, fnom which leads pipe 52. This pipe extends through hollow shaft 422 end flows into the distribui'tng device =14, from which the water flows upward through the hollow shaft 42 and into the bowl carried h shaft 4:2. The bottom portion of e bowl 533 is pro ided with Iiil ilil aperture ihro'ngh which water is 5? g which evcl gemn'heel similar. to that provided tenor o drives; so

(2 extending upwardly their Iiistirring inemli crs,

Connected with ipe 63 similarly W from the e casing c121, and means 9.5 shown seas to dischiirgewater into the. legs 18 and- 20. e The water dischargedthrough the lower open end of these forked portions flows upward through thehollow shaft and discharged upon the cover 2, whence it posscs through channels '60 formed upon the ,cover portion. these channels are pipes :31, each of which 'extends downwardly to the twyer boxes, and then inward toward the center of the pro ducer to a point concentric with the axis of the stirring members 11. The pipes at these points are provided with swiveled joints as at 02, from which leads a forked to enter legs 13 an 14; the returning water flowing downward through the hollow shaft 21, the lower end of which is constricted so that the stirringmember 11 is at all times fiill o'f water. lhis Water is then dischargedinto the receptacle 5.

It. will be accordingly seen that I'have a construction. well adapted,- among others, to attain the aims and objects sought to he covered, in a simple yet efficient manner. By means of the peculiar construction, the mass within the producer will at all times he thoroughly agitated, and the formation of crevices therein prevented, insuring the proi'inction of gas of even qunlitv and; also, insuring a steady and uninterrupted low thereof.

AS many Changes could he made in the shove construction and loony apparently different embodiments of this invention could he made'withont dcpartin scopetlrereof, it is intended that matter contained in the above descriptionor shown in the accompanying drawings shall be in tc'rpretcd as illustrative and not in a limiting sense. o

It is also-to be understood that the lam gnngc used in the following claims is im tended to cover all of the generic and specific features of the invention herein described and all statements of -thc scooe of the invention, which as a matter of language, mighl he said to fall therehetwecn.
